摘要： The image forming apparatus has a developer container containing a developer therein, a developer toner density detecting portion for detecting the permeability of the developer in the developer container to thereby detect toner density, and an engine controller for detecting whether the image forming apparatus has gone wrong, on the basis of the toner density detected by the developer toner density detecting portion. Thereby, it becomes possible to detect the failure of a developing apparatus reliably and early by an inexpensive construction.

摘要： An electrical contact member is usable with a process cartridge, and is for establishing an electrical connection between the process cartridge and a main assembly of an electrophotographic image forming apparatus, when the process cartridge is mounted to the main assembly of the apparatus. The process cartridge includes an electrophotographic photosensitive drum and a process device actable on the photosensitive drum. The electrical contact member includes: a base member; a mounting portion for mounting the base member to a frame of the process cartridge; a positioning portion for positioning the base member in the frame when the base member is mounted to the frame of the process cartridge by the mounting portion; and an electrical contact portion, projected from the base member, for establishing an electrical connection with a main assembly side electrical contact member, which is provided in the main assembly of the apparatus, by pressing in a direction against the main assembly side electrical contact member when the process cartridge is mounted to the main assembly of apparatus. This direction is different from a mounting direction in which the process cartridge is mounted to the main assembly of the apparatus.
